Preview your artwork in a 16:9 video frame, then download a standard 1280 × 720 thumbnail image.
How to preview and export a thumbnail
- Choose an image from your device. A 16:9 image gives you the most predictable framing.
- Review the thumbnail preview and check that the main subject and headline remain clear.
- Select Download 1280 × 720 to save the PNG.
- Open the downloaded image and inspect the crop before uploading it to your publishing platform.
Check the crop before you publish
The export fills a 1280 × 720 canvas with a centered crop. If your source image has different proportions, some edges will be removed. This tool does not provide crop-position controls. Use the Social Media Image Resizer if you need to reposition the crop, keep the whole image with padding, or choose other dimensions.
Tool output and YouTube guidance
1280 × 720 is the output size provided by this tool. It is not a claim about YouTube’s latest recommended resolution or upload-size limit. See YouTube’s current thumbnail guidance for the requirements that apply to your video type and upload device.
For a useful readability check, view the downloaded artwork at a small size as well as full size. A short headline and a clear subject are easier to judge than a crowded composition.
Frequently asked questions
What file does the tool export?
It exports a static PNG that is 1280 pixels wide and 720 pixels high, with a 16:9 aspect ratio.
Can I preview YouTube search or mobile feed layouts?
The current tool provides a simple 16:9 image preview. It does not reproduce the search results page, mobile feed, title truncation or the appearance of every YouTube surface.
Will it tell me which thumbnail gets more clicks?
No. The tool does not run an audience test, calculate a click-through score or predict engagement. Use it to inspect artwork and framing.
Can it extract a frame from a video?
This tool accepts an image. Save a frame with your video editor first, then select that image here.
Why can the PNG be larger than my original JPG?
PNG and JPG store images differently. Converting a compressed photo to PNG can increase file size. Check your publishing limit and use the image resizer’s JPG option if that better suits your artwork.
